North (1.52) West (1.31) and South (1.14).

Population is near normal and at moderate level. It will increase rapidly and enter
the high range before mid-July, then decrease. Highest districts are East (1.61) and
West (1.06).
Spray Notes: The summer spray is usually timed to control rust mite before the summer in-
crease has built up heavy infestations. This spray is also for general clean up of scales,
whiteflies, spider mites and mealybugs; hence it should be thoroughly applied in ample
volume to wet foliage, fruit and wood. This is especially true where snow scale is to be
controlled.
